Re: [T3] Type engine longevity

             I'm sorry, but the T4 case, which of 
course is made of much stronger aluminum and not
magnesium, along with it's through bolt case design,
is FAR superior to the type 1/3 case. Basically, the
only weakness that the type 4 has, is the tendency
for factory, unaltered heads to drop valve seats,
therefore usually causing the engine to self destruct.
Any competent rebuilder has these heads modified with
different seat material and has the seats machined
with a tighter interferance fit, thereby completely
solving the dropped seat problem. The addition of
factory oil filtration doesn't hurt either ;) True,
they are a different and somewhat more complicated
animal to those who are used to wrenching on type 1/3
engines exclusivly, but if built right, can take FAR
more abuse than a comparitivly sized type 1/3 engine.
Leon, this may be an alternative for you ;) The only
thing for me, is that I would like to keep my car
somewhat stock appearing and do not want to go through
the many hassles of installing the type 4 ( the hassles
aren't that many, but can be a tad expensive to
overcome).

>Who will build it?

                    I will, of course :)
